A new study suggests that large swings in when people go to bed could double the risk of serious cardiac events—particularly among those who get less than eight hours of sleep. By contrast, irregular wake-up times showed no clear link to cardiac events

Analysis Summary
This is real — a legitimate Finnish study of 3,200+ people found that inconsistent bedtimes roughly doubled the risk of major heart events, but only in people sleeping under 8 hours. Irregular wake-up times didn't increase risk. The study is peer-reviewed (BMC Cardiovascular Disorders, 2026) and tracked people over a decade using healthcare records. The post accurately summarizes the main findings, though it doesn't mention this was a specific cohort born in 1966, so results may not apply equally to all ages or populations.
Claims Analysis (3)
“Large swings in when people go to bed could double the risk of serious cardiac events”
Study found inconsistent bedtimes associated with roughly twice the risk of major cardiovascular events in short sleepers.
“This effect is particularly pronounced among those who get less than eight hours of sleep”
Article explicitly states the doubled risk applies to the group with less than eight hours in bed.
“Irregular wake-up times showed no clear link to cardiac events”
Article directly states this finding from the study.
